Description
Technical field
The present invention relates to mechanical braking technical field, and in particular to a kind of self-locking floating brake lining.
Background technology
At present, in high-speed train braking device, generally use is disc type brake structure.Disc type brake structure mainly includes
Brake disc and brake pad, above-mentioned brake structure by brake disc and the phase mutual friction of brake pad, consume moving vehicle or
The kinetic energy of equipment, make train stop motion.But due to the mode that brake pad is generally fixedly connected using rivet, institute
In braking, easily to there is the phenomenon that can not be bonded completely between the brake pad on brake pad and brake disc, make active force not
Energy is average to be acted in brake pad and brake disc, so as to cause the cracked high stress of brake pad point, chip off-falling, lack
Damage, produce area of localized hyperthermia, shortened the service life of brake pad, influence braking effect.
Single-point floating brake lining can efficiently solve during the operation of high speed/motor train unit train and alleviate brake disc hot spot
With crackle, avoid brake lining from rubbing partially, improve insensitivity.The single-point floating brake lining of existing structure shares 18 friction pieces, friction
Body influences independently of on backboard because friction piece rotation exists on the braking ability of brake lining, therefore in order to avoid friction piece revolves
Turn, be typically employed in the periphery fixing rivet of friction piece in the prior art, so as to prevent from propping up friction piece rotation, in general one
Piece brake lining needs to rivet 30 anti-rotation rivets, and this results in this brake lining low production efficiency, and production cost is high；Another aspect rivet
Stress is easily damaged, and it is unreliable to also result in anti-rotation performance.
The content of the invention
Therefore, the technical problem to be solved in the present invention is to overcome on self-locking floating brake lining dorsulum of the prior art
The multiple rivets of processing need to be installed, so as to cause production cost high, low production efficiency, and prevent that the performance that friction piece rotates is unreliable
Technological deficiency, can reduce production cost so as to provide one kind, improve production efficiency, and the performance for preventing friction piece from rotating
Reliable self-locking floating brake lining.
In order to solve the above technical problems, the present invention provides a kind of self-locking floating brake lining, including：Backboard, it is some fixed to have
Position hole；
Friction piece, elastic floating is arranged in the positioning hole, and the friction piece is convex in the backboard,
There is the first gap for any friction piece can be made to rotate between the adjacent friction piece, all friction body phases
It is adjacent successively against so as to producing the gap of self-locking.
Above-mentioned self-locking floating brake lining, first gap are in 0.5-5mm sections.
Above-mentioned self-locking floating brake lining, the friction piece are Long Circle.
Above-mentioned self-locking floating brake lining, the friction piece is arranged on the backboard with several columns, and each column is described
Friction piece length direction is end to end.
Above-mentioned self-locking floating brake lining, the friction piece are 20.
Above-mentioned self-locking floating brake lining, the friction piece are arranged to 8 row on the backboard, wherein first row and last
One row have a friction piece respectively, and secondary series to the 6th row has three friction pieces respectively.
Above-mentioned self-locking floating brake lining, the friction piece include：The supporting part of spherical structure and from the supporting part to
The location division of lower extension, the location division are stretched into the positioning hole, are set between the top surface of the supporting part and the positioning hole
Jump ring is equipped with, sets and has elastic component between the location division and the bottom surface of the positioning hole.
Technical solution of the present invention, have the following advantages that：
1. in self-locking floating brake lining provided by the invention, pass through the setting in first gap so that any one rubs
Rub body can be resisted against on adjacent friction piece when stress rotates, and adjacent friction piece is again successively by rotating torque
To friction piece transmission adjacent thereto, when being acted on so as to reach any friction piece by rotating torque, all friction pieces simultaneously by
Acted on to rotating torque, so as to reach the effect of self-locking.Compared in the prior art, using the technical scheme of rivet backstop anti-rotation
For, technical scheme eliminates and rivet is processed on backboard, therefore can play reduction procedure of processing, reduces production
The effect of cost.
2. in self-locking floating brake lining provided by the invention, the first gap is due to being that disclosure satisfy that any friction piece occurs
Rotate, all friction pieces are adjacent successively against so as to producing the gap of self-locking.Therefore the distance in the first gap is actual very small, this
Sample sets more friction pieces compared to can be arranged on for existing brake lining on same big backboard, so as to improve the present invention
Self-locking floating brake lining braking effect and service life.
